Note 1: The required bootstrap capacitance value varies according to the motor drive conditions. The capacitor is

Do not exceed a detection current of 1A when using this product.

(Please go from the outside in the over current protection.)

Note 3: When using this product, some adjustment is required in accordance with the use environment. When

mounting, place as close to the base of this product leads as possible to improve the ripple and noise

elimination.

Note 4: The DIAG pin is open drain. Note that when the DIAG pin is connected to a power supply with a voltage

using the DIAG pin, connect to the GND.

Handling precautions

(1)

Note that if the power supply is switched off as described above, this product may be destroyed if the

a relay or similar while the motor is still running.

(2)

The excess voltage such as the voltage serge which exceed the maximum rating is added, for example,

may destroy the circuit. Accordingly, be careful of handling this product or of surge voltage in its

application environment.
